Abstract

The invention relates to the field of agriculture, in particular, to machines for harvesting tall stem bast crops. The purpose of the invention is to improve the quality of bast by reducing the steadiness of the stems. The harvester for harvesting tall-stemmed lab cultures contains a combing mechanism.

The elastic straps mounted on the belt of the comlivating mechanism capture the butt part of the stems and transport them to the peeling part, at the same time aligning them. 4 il.

Description

The invention relates to agriculture, in particular to machines for harvesting tall stem bast crops, mainly kenaf.

The purpose of the invention is to improve the quality of bast by reducing the steadiness of the stems.

FIG. 1 shows a combine harvester for harvesting tall-stemmed bast crops, top view; in fig. 2 is a section A-A in FIG. one; in fig. 3 - komlepodbirayuschiy mechanism; in fig. 4 is a view B in FIG. 3.

The harvester for harvesting tall-stemmed pebble crops contains frame 1, on which dividers 2 with stem lifters 3 are fixed, behind them is a block of clamping conveyors 4. below which there is a cutting unit 5 and a grass separator 6 in the front part, and three-chain chain-finger cross conveyor 8 for moving the stems. In the front part 9 of the table 7, along the combine at an acute angle / movement of the chains of the cross conveyor, there is a hammering mechanism 10. Further along the technological chain are flatting 11 and supporting 12 rollers, lumber bar 13, a mobile drum 14 and a portable conveyor 15 with a rake portion 16 .

Komplegodivaya mechanism 10 contains the leading 17 and driven 18 pulleys, covered by a belt 19 with concave elastic transport strips

20 radius R. The lower part of the combination punching mechanism 10 is located in the neckline

21 desk 7 below its outer surface.

The harvester is a trailed machine and is aggregated with wheeled tractors.

any class. The working bodies have a tractor power take-off (not shown).

Combine for harvesting tall-stemmed bast crops works as follows.

When the harvester moves across the field, the stalks of one row are separated from the array by stem by dalters 2 and stem lifters 3 are fed by the apical part to the block of clamping conveyors 4. The stalks clamped between the belts of the conveyor are cut by the cutting unit 5, stripped from the grass and trimmed (underdeveloped the stems with the fingers of the grass separator 6 and placed on the flat table 7 of the transverse conveyor 8. The fingers of the transverse conveyor 8 extending from the cuts of the table grab the stems and move them to the harvester separator.

The machine-selecting mechanism 10 aligns the mass of the stems by the comms and, together with the transverse conveyor 8, moves it to the ivy 11 and supports it; living 12 rolls. The stalks, the passage between them, squash, thereby weakening the connection between the phloem and the wood. The flattened stems, the passage through the interaction zone of the lumber bar 13 and the bilar drum 14, are separated from the fires. The bast obtained therewith is removed from the treatment zone by the external conveyor 15 and, after being formed in a portion by a rake portion, the stacker 16 is laid on the ridge of a beveled row to dry.

Komplebing mechanism 10 works in combination with a cross-chain-finger conveyor 8. Getting

the drive from the drive pulley 17, the belt 19 transmits rotation to the driven pulley 18. The concave elastic transporting strips mounted on the belt 20 (facing

the concave surface along the belt), moving on the belt, seize the butt part of the stems and transport them to the separating part, at the same time leveling by the value of I

(Fig. 3).

At the same time, the normal N forces arising in the process of movement on the concave surface of the elastic strips 20 stabilize the process, preventing the butt of the stems from slipping out of the upper edge of the belt 19 and pinching them between the belt and the edge of the table cutout 21. The directivity of normal forces N along the radius of the concavity of the slats contributes

Claims (1)

the formation of single-layer stalks fed to the pulper. Claims of the invention: Combine for harvesting high-stemmed lab crops containing frame-mounted stem plants, located between the clamping conveyors and the cross conveyor at an obtuse angle to the latter and under the sharp, to the clamping conveyors, a belt-cleaning mechanism with a vertically mounted tape, different so that, in order to improve the quality of bast by reducing the steadiness of the stems, The belt of the combining mechanism is attached to elastic arcuate strips facing the device for treating the stems with a concave surface. // 12 2 tt nineteen Aa /////, 2 you go p Fig.Z Wi ft  Mlrim
